After two weeks of the Fire Festival, Hearthstone is kicking off a new Frost Festival with a free Arena run and a chance to earn a free pack for the next expansion.

If you've been playing Hearthstone the last two weeks, you've been enjoying the Fire Festival. Now Blizzard is kicking off the Frost Festival, which is bringing some Arena-focused perks, some cosmetics, and a Lich King-themed Tavern Brawl.

Logging in at any time during the event will get you a free Arena run. Even better, you'll start all Arena runs during the Frost Festival with a free win. That means even if you lose every match, you'll finish with a win. Additionally, completing three Arena games during the event will get you a free card pack from the upcoming Knights of the Frozen Throne expansion. You'll have to wait for the expansion to launch to open it, of course.

The Frost Festival is ongoing now, so you can check it out just by jumping into the game.
